NAME

       gnutls_record_recv - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       ssize_t gnutls_record_recv(gnutls_session_t session, void * data, size_t data_size);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       void * data the buffer that the data will be read into

       size_t data_size
                   the number of requested bytes

DESCRIPTION

       This  function  has  the  similar semantics with recv().  The only difference is that it accepts a GnuTLS
       session, and uses different error codes.  In the special case that the peer requests a renegotiation, the
       caller  will  receive  an  error  code of GNUTLS_E_REHANDSHAKE.  In case of a client, this message may be
       simply ignored, replied with an  alert  GNUTLS_A_NO_RENEGOTIATION,  or  replied  with  a  new  handshake,
       depending  on  the client's will. A server receiving this error code can only initiate a new handshake or
       terminate the session.

       If EINTR is returned by the internal pull function (the default is recv()) then GNUTLS_E_INTERRUPTED will
       be returned.  If GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must call this function again to
       get the data.  See also gnutls_record_get_direction().

RETURNS

       The number of bytes received and zero on EOF (for stream connections).  A negative error code is returned
       in case of an error.  The number of bytes received might be less than the requested  data_size .
